DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. Embodiment 1 FIG. 1 is an exploded perspective view of a tool. FIG. 2 is a schematic front view of the tool as viewed from the direction of arrow A in FIG.

Mounting plate 3 for tool 1 using selective holder
Is formed of a metal plate, and two cam bodies 5 and 7 are symmetrically mounted on the front surface of the mounting plate 3 at a required interval so as to be rotatable around a screw 3a. Protruding cams 5a, 7a formed of circular arcs having a predetermined curvature are provided at the upper ends of the cam bodies 5, 7.
However, concave cam surfaces 5b, 7b each having a curvature corresponding to the protruding cams 5a, 7a are formed on both sides of the base end.

At the base end of each cam body 5, 7, an arm 5c, 7c extends a predetermined length in a tangential direction of a circle supposed to pass through the outer peripheral surface of the protruding cams 5a, 7a. And each cam body 5, 7 with respect to the mounting plate 3.
When one cam body 5 (7) is rotated, the protruding cam 5a (7a) is turned into the other concave cam surface 7b (cam 5a).
Are set to be in sliding contact with each other.

Tool portions 5d and 7d of different sizes are integrally formed at the tips of the arms 5c and 7c. The tool portions 5d and 7d include, for example, hexagon wrenches, spanners, (+) or (-) shaped drivers (screwdrivers), gap gauges, and the like having different sizes.
The case where d is a hexagon wrench is shown.

A gripping member 9 is mounted on the mounting plate 3 on which the cams 5 and 7 are mounted. The gripping member 9
Has a shape of a pair of half-cylinders or prisms. The two are fixed by screws 9b to clamp and fix the mounting plate 3. A housing recess 9a for housing the arms 5c, 7c to be folded is formed on the side surface of the mating portion of the gripping member 9 in the axial direction.

Next, a method of using the above-described tool will be described. FIG. 3 is an explanatory diagram showing a use state.

First, when not in use, each of the cam bodies 5, 7
Is folded and accommodated so that the arm portions 5c and 7c are positioned within the accommodation recess 9a of the gripping member 9. At this time, the concave cam surfaces 5b and 7b at the base ends of the cam bodies 5 and 7 are opposed to each other.

Next, for example, the right tool portion 7d shown in FIG.
Is selected, the cam 7 is rotated about 180 degrees in the counterclockwise direction in a state where the other cam body 5 is housed in the housing recess 9a to protrude from the gripping member 9. At this time, the protruding cam 7a of the rotated cam body 7 comes into sliding contact with the concave cam surface 5b of the other cam body 5 to allow the rotating operation. When the cam body 7 is rotated about 180 degrees in the counterclockwise direction from the folded state located in the accommodation recess 9a, the projecting cam on the other cam body 5 is formed on the concave cam surface 7b of the cam body 7. 5a abuts and fixes the cam body 7 while keeping the rotating state constant.

As a result, the cam body 7 extends linearly with respect to the gripping member 9 and is kept in a detented state.
The tool part 7d can be used efficiently.

When the tool portion 5d of the other cam body 5 is used, the cam body 7 is rotated clockwise approximately 180 degrees to be folded and accommodated in the accommodating recess 9a of the gripping member 9, and thereafter, The other cam body 5 is turned 180
The cam body 5 is extended substantially linearly with respect to the gripping member 9 to be fixed.

In this embodiment, since two types of cam bodies 5.7 having different sizes of tool parts 5d and 7d are mounted on the mounting plate 3 in the same plane, the thickness of the tool 1 itself is reduced. can do.

Further, one of the cam bodies 5 (7) selected by the protruding cams 5a, 7a and the concave cam surfaces 5b, 7b provided at the base end of each cam body 5, 7 is allowed to rotate. When the cam body 5 (7) is rotated substantially linearly with respect to the gripping member 9, the rotating state of the cam body 5 (7) is maintained by the mutual engagement, and the tool parts 5d and 7d are efficiently used. Can be used

Embodiment 2 FIG. 4 is an exploded perspective view of a tool.

According to the present embodiment, the tool 21 using the selective holder is provided on the surface side of the mounting plate 3 with the cam body 5.
7 has a structure in which two cam bodies 23 and 25 of different sizes or types are rotatably supported on the back side in a symmetrical positional relationship. A tool portion 23d formed at the tip of the arm portion 23c / 25c in each cam body 23/25.
25d may have a different size or a different type from the tool portions 5d and 7d described above.

That is, when the tool portions 5d and 7d of the cam bodies 5 and 7 are hexagonal wrenches, hexagonal wrenches of different sizes may be used, or the tool portions 23d and 25d may be different types of spanners.

In the tool 21 shown in FIG. 4, the same members as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted. Also, the method of using the tool 21 is the same as that of the first embodiment, and the description thereof is omitted.

In this embodiment, four different types of cams 5
In spite of the fact that 7, 23 and 25 can be folded and accommodated, the thickness of the tool 21 can be reduced to a thickness corresponding to two cam bodies.

The above-mentioned tools 1, 21 are provided with cam bodies 5, 7, 2
The mounting plate 3 on which the mounting plates 3 and 25 are mounted is pinched and fixed by a pair of gripping members 9 so that the turning operation can be easily performed. However, as shown in FIG. 2 screws 9b used to fix the half-column or prism-shaped gripping members 9 to each other without providing
The cam members 5, 7, 23, 25 may be rotatably supported by the above.

In the above description, the cam bodies 5, 7, 23.2
The description has been given of the case where the tool portions 5d, 7d, 23d, and 25d are integrally formed at the tip of the tool 5 to form the tools 1.21, but the tool mounting portions are respectively provided at the tips of the cam bodies 5.7, 23, and 25. It is good also as a selection holding tool which makes it possible to attach and detach a tool.

In the above description, the tool provided with the tool portion at the tip of the arm portion of the cam body is described. However, the member provided on the selective holder is not limited to the tool. In any case, it is sufficient that the plurality of cam bodies can be compactly accommodated, but at the time of use, only the selected members can be held in a usable state.

[0032]

According to the present invention, a plurality of tools having different sizes can be compactly folded and accommodated, and the size can be reduced. The present invention also provides the selected desired tool,
Workability can be improved by fixing to a usable position.
